Minor improvements and bug fixing

- Enhanced the "Annotation are Easy" chart with new features: Text Annotation with Background, Axis Marker Custom Annotation, and Image Annotation. - "Image Annotation" example demonstrates different use cases of Image Annotation. - Demonstrated enabling and disabling dragging the tooltip over the Axis area. - Addressed minor bugs for improved performance.

Now you can enable/disable the modifier's application on Axis.

Implement new examples * Pan zoom a dynamic series chart - Demonstrate the use of the pinch and pan zoom modifiers for dynamic series, as well as the ZoomState property. * Chart inside scroll - Demonstrate how charts can be scrolled inside a scroll view using the setDisableTouchEvent method.

New examples: - Index Date Axis - Population Pyramid - Depth Chart - Fixed size axis

Create Custom Animations examples: - Animating Line Chart - Animating Stacked Column Chart

- Bug fixes and performance - Upgraded SciChart library to version 4.3.1

- Fixed Pie/Donut Chart drawing frame - Fixed Bubble series zScaleFactor dynamic update - Fix applying background color in some examples - Fixed examples settings popups, for older version iPads, such as 12.x

The SciChart v4 adds a new platform and introduces the macOS support. This means that applications with SciChart can now be run on iPhone, iPads and macOS laptops. All the features available with our iOS charts are now supported for macOS. That includes all the 2D and 3D chart types, many axis types, interaction with the charts, synchronizing multiple charts, markers, and annotations and more. SciChart is a fully hardware-accelerated (OpenGL, Metal) 2D & 3D chart component allowing you to make impossible projects possible.

The biggest thing we’ve added in SciChart Mobile v3 is Realtime 3D Charts on mobile devices. Bringing the ability to visualize all kinds of 3D Data, from Surface Meshes for scientific plots, to 3D Point-Clouds for LIDAR data, to 3D Bubble or Scatter charts, 3D Column Charts and more to Mobile devices. SciChart is a fully hardware-accelerated (OpenGL, Metal) 2D & 3D chart component allowing you to make impossible projects possible.
